7. An in-band optical signal is a pulse/sequence where the peak wavelength,

λp, is defined as 850 nm ≤λp ≤ 900 nm, and the pulse

characteristics are compliant with the IrDA Serial Infrared Physical Layer Link Specification.

Infrared Reflow Profile

All HSDL-1100 IR transceivers are classified as IEC 825-1 Accessible Emission Limit (AEL) Class 1 based upon the

current proposed draft scheduled to go into effect on January 1, 1997. AEL Class 1 LED devices are considered eye safe.

See Hewlett-Packard Application Note 1094 for more information.
